Android/iOS/BlackBerry: You're enjoying a great bottle of red with dinner, or at a friend's, and you want to remember it. Rather than relying on tannin-clouded memory or easily forgotten notes, snap a pic with Vivino and let the app identify your wine.

As you might expect, Vivino offers social connections through Twitter and Facebook, so you can brag to friends about really great finds.

As for its touted ability to match a picture to its database of around 400,000 labels, it came out at the app's stated success rate, 32 percent: one out of three bottles I happened to have in the house were identifiable, although our bottles tend to be whatever friends left at our place. Even if Vivino doesn't catch your bottle, it keeps the picture stashed away, so you can always manually identify your good wine in an app where you'd think to look for it.

Vivino is a free app, in beta at the moment, for iOS, Android, and BlackBerry phones. If you've got a better wine cataloging/finding system in place (Evernote, maybe?), tell us in the comments.
